1.0 Introduction

This manual describes the Horner Electric Metasys Interface module (M/N 2MT3000), which implements theJohnson Controls Metasys N2 protocol. The interface module is designed to allow VTAC 7 and GV3000 drivesto be operated and monitored via the Metasys network.

The Metasys Interface mounts below the Regulator board on the VTAC 7 and GV3000 drives and connects to theRegulator via a flexible ribbon cable. Power for the Metasys Interface comes from the drive through the Regulator.

The drive is configured by using the keypad or the CS3000 software. The Metasys network can then operate andmonitor the drive.

More Information

Before attempting to install and use the Metasys Interface, make sure you have read and understood the VTAC 7 orGV3000 instruction manual and any pertinent documentation for the Metasys N2 network from Johnson Controls.This instruction manual does not explain drive operation or Metasys network installation and programming.

Basic Installation and Operation Steps

This section describes how to install and operate the Metasys Interface. Chapter 3 in this instruction manualdescribes installing the module in more detail. This manual assumes that the Metasys network has already beeninstalled and configured properly.

1. Install and wire the VTAC 7 or GV3000 drive.

2. Install the Metasys module in the drive. See chapter 3 for installation instructions.

3. Connect the Metasys module to the Metasys network.

2.0 Mechanical/Electrical Description

The Metasys Interface board is a printed circuit board that mounts inside the VTAC 7 or GV3000 drive as anoption board. It connects to the drive regulator via ribbon cable. It connects to the Metasys network via an RS-485port. See the figure below for a port pinout.

Two LEDs next to the network port provide status information about the board. The LED closest to the port(labeled HEALTH) flashes alternately red and green for four seconds when the board is first powered up. After thisinitial power-up period, the LED remains green as long as the board is functioning correctly. If the LED becomesred after the initial period, check the connection between the VTAC 7 regulator board and the Metasys board.

The second LED (labeled COMM) indicates communication status. During normal drive operation, this LEDshould flash green. The flashing is synchronized to the polling commands from the Metasys host. The rate offlashing will be determined by the poll rate. If this LED fails to flash or is always on or off, the board is notreceiving poll commands from the network. This problem can be caused by the following conditions:

• Faulty network connection• Metasys host not configured to send poll commands to Interface board• Interface board drop address incorrect in VTAC 7 drive parameter P.060

The Interface board supplies a 120 ohm resistor for termination of the receive signal lines from the network. Thisresistor must be connected only on Interface boards at the two farthest ends of the network cable. To use theresistor, install a jumper wire between pins 9 and 10 on the connector. This is normally done inside the connectorhousing on the end of the cable.

Figure 2.1 - Metasys Port Pinout

For use with the Metasys N2 Protocol. The user will need to provide a 15-pin male D-shell connector withinsulated wire jumpers between pins 10-12 and 11-13.

Slide the MetasysInterface board up behind the Regulator board and align the Metasys Interface board's four mountingholes with the four standoffs on the drive. Fasten the board to the drive with four (4) 7/32" nuts. Metalnuts must be used for proper grounding of the Metasys Interface board.

Step 5. Align the key on the Regulator board's 34-conductor ribbon cable connector with the slot in the MetasysInterface board's connector and press the ribbon cable connector in until it locks into place.

Step 6. Route the network cable through the signal wiring tray on the right side of the drive.Step 7. Close and secure the outer cabinet door of the drive.

3.6 Connecting the GV3000 or VTAC 7 Drive to an N2 Communications Bus

When connecting to the N2 Communications Bus, the GV3000 or VTAC 7 drive should be wired with the samecabling and termination as other devices on the network (see figure 3.7). If the GV3000 or VTAC 7 drive is at theend of the cable system, it must be terminated by installing a jumper wire between pins 9 and 10 on the RS-485connector, which will enable the supplied 120 ohm resistor on the Metasys Interface board. Refer to the N2Communication Bus manual for a detailed description of how to add a device to the N2 Bus.

4.0 Data Types and Transfer Rates

In order to minimize regulator board CPU loading, the transfer of data to/from the drive regulator board will notoccur at all times and will not occur at the same rate. The sections that follow describe the data types for input andoutput data, along with typical drive information in each category.

4.1 Input Data

The drive input data is categorized as one of three types: Control/Reference, Tunable, or Configurable.

Control/Reference inputs include data which require fast update rates. This includes data such as sequencing inputs(Start, Stop, Run/Jog, Fwd/Rev, etc.) and speed/torque reference. Control/Reference inputs are transferred from theMetasys Interface board to the regulator board every speed loop scan period (every 5 msec), or as often as it isrequired by the drive. For example, if the drive is configured to obtain its torque reference from the option port, itwill read this data from the option port every torque loop control scan.

Tunable inputs include parameters which typically require modification or adjustment while the drive is running.Tunable data includes parameters such as accel/decel rates, min/max limits, gains or offsets, etc. Tunable inputsare transferred from the Metasys Interface board to the regulator board whenever the regulator performs theprocessing of new tunable parameters. This occurs approximately every 100 msec while the drive is running orstopped.

Configurable inputs include parameters which alter the way that the drive operates in such a way that they cannotbe modified while the drive is running. Configuration data includes parameters such as reference source selection,I/O configuration, motor/tach nameplate data, etc. Configurable inputs are transferred from the Metasys Interfaceboard to the regulator board whenever the regulator performs the processing of new configuration parameters. Thisoccurs approximately every 100 msec while the drive is stopped. Values sent from the network master while thedrive is running will not be read in and used by the drive regulator until the drive is stopped.

4.2 Output Data

The drive output data is categorized as one of two types: Runtime signal data or Tunable, Configuration, andStatus data.

Runtime Signal data includes things such as selected speed reference value, sequencing status (ready, running,etc.), drive fault flags, terminal block digital inputs state, and front–panel display mode values (RPM, VOLTS,AMPS). This information is transferred from the regulator board to the Metasys Interface board every speed loopscan period (every 5 msec).

Tunable, Configuration, and Status data includes all other information provided by the drive which is not definedas Runtime Signal data. This would typically include all drive parameter values. Tunable, Configuration, andStatus data are transferred from the regulator board to the Metasys Interface board whenever the regulator performsthe processing of new tunable and configurable input parameters. This occurs approximately every 100 msec.

4.3 Input Transfer Enables

The Metasys Interface board must be actively communicating with the master and it must be selected as the drivecontrol source (P.000 = OP) in order for any inputs to be transferred from the Metasys Interface board to the driveregulator. Note that the keypad can still be used to change parameter values when the drive control source is theoption port. However, any changes made via the keypad will be overwritten when the next network update occurs.

4-2

This should be kept in mind if parameter changes need to be made while the option port is the control source forthe drive.

NOTE: Downloading a configuration from the serial port will not be permitted while the option port is theselected drive control source.

In addition, a network–master–controlled Tune/Config Input Enable bit is provided to enable the transfer oftunable and configurable inputs from the Metasys Interface board to the drive regulator. Until this bit is set ON(1), only control/reference data are read in by the drive. This gives the master’s application program directcontrol over when tunable and configurable parameter values are read in by the drive, if at all.

For example, the master application program would typically initialize the tunable and configurable parameter datain the master’s network card dual–port memory before turning on the Tune/Config Input Enable bit.

Another example would be an application which only wants to send control/reference data to the drive. In this case,the master would always leave the Tune/Config Input Enable bit OFF. The drive would then be configured locally,but start, stop, reset, and reference would be sent from the network master.

4.4 Output Transfer Enables

All output data provided, based on drive connection type, is transferred to the Metasys Interface board at all times.The network does not have to be active and the option port does not have to be selected as the drive control source(P.000). No output enable control bit is necessary.

4.5 I/O Update Enable Logic Summary

The following logic strings summarize the output and input enable logic described in sections 4.3 and 4.4.

4.6 Tune/Config Update Synchronization Flag

To allow the network master’s application program to determine when tunable and configurable inputs have beenupdated in the drive, a master write bit is provided which is copied to a master read bit by the drive. The drive willcopy the master write bit to the master read bit after the drive has read in and processed all tunable and/orconfigurable inputs. The Tune/Config Input enable bit must be set (1) in order for this to happen. Note thatconfigurable type inputs are only read in by the drive while it is not running. This will not affect the copying of thenetwork synchronization bit since tunable inputs will still be transferred.

The tune/config update synchronization flag is defined in the first drop of the drive network drop connection.Therefore, it can only be used to indicate to the master when data for the first drop has been read in and processedby the drive.

By toggling the network synchronization bit in the master and by monitoring the copied value from the drive, themaster’s application program can determine when the drive has read in that data. This feature is provided for thoseapplications which may require this type of synchronization. However, it is not necessary for the master’sapplication program to use it, as it has no affect on drive operation.

To determine when changes to tunable and configurable data on the drive have been completed, the master wouldperform the following sequence:

Step 1. Modify the tunable and/or configurable data.Step 2. Set the Tune/Config Input enable flag (if not already set).Step 3. Toggle the network synchronization flag.Step 4. Monitor the loopbacked copy of the network synchronization flag until it equals the value written in step

3.

Another synchronization method is to verify that the output data from the drive matches the input data written tothe drive. All data written to the drive can be fed back to the master. This may be the best alternative if fullconnection synchronization is required.

4.7 Parameter Processing Error Flag

A parameter processing error status flag is provided to allow the network master to determine whether anyparameter values are unacceptable to the drive. If this flag is set (1), then one or more parameters sent to the drivewere rejected. If this flag is not set (0), then all parameters sent to the drive were accepted. Note that theTune/Config inputs enable bit must be set (1) before the drive can read in, and consequently process, anytune/config parameters. The parameter processing error flag is updated approximately every 150 msec.

4.8 Data Retention Timing Requirements

All tunable and configurable drive input values must be maintained by the network master’s application programfor at least 150 msec to assure that they are seen by the drive. This is particularly relevant for data which istransition–detected by the drive.

Control/Reference data types generally do not have this 150 msec. requirement since they are scanned (read in) bythe drive every 5 msec. Special cases to this rule are the Start input and the Error Log Clear command input.

The Start input requires a 0 to 1 transition in order to start the drive. The Start input from the network may bedelayed by the drive for up to 100 msec. This is done to synchronize a drive start to the processing of newconfigurable data. In order for the network master to assure this 0 to 1 transition is detected by the drive, the

4-4

network master must maintain both the 0 and 1 states for at least 100 msec. Values which are maintained for lesstime may not be detected by the drive.

The Error Log Clear command bit is processed at least every 150 msec even though it is defined in theControl/Reference data section. A 0 to 1 transition must be detected by the drive after the network is active andthe control source has been selected to be the option port for the error log to be cleared. In order for the networkmaster to assure this 0 to 1 transition is detected by the drive, it must maintain both the 0 and 1 states for at least150 msec.

4.9 Drive Ready Status Bit

The Drive Ready status bit is used to indicate that a 0 to 1 transition on the start input will start the drive. TheDrive Ready bit will be ON (1) when all of the following conditions are met, and OFF (0) when one or more arenot met:• No drive faults are active• Stop input is ON (1)• Front–panel STOP/RESET button is not pressed• Function loss TB input is closed• A download from the serial port (using the CS3000) is not in progress• On larger drives (>50 HP) which contain a DC bus pre–charge resistor bypass relay, the pre–charge relay must

be closed.
